One Object of this invention is to provide a novel valve adapted to be placed in the outfall line of a sewage system, to preventwater from backing up into the system, from Q pass flow will be under the control of an operator.

' A preferred form has been shown in. the 1 drawings, but it will be understood that a 15 mechanic, working within the scope of what is claimed, may makesuch changes as his skill may suggest, without departing from g 'wise of thepipe 2 in parallel relation to the I anchor 22. The anchor 22 and the foot-piece :23 are disposed onoppositesides of'the openthe spirit of the invention.

The numeral 1 designates a sewerage disposal plant, to which the sewage is supplied through an inlet pipe 2. At the inner end of the pipe 2, there are vertical guides 3 in which a gate 4 is adjustable. The gate 4: has a handle 5 by which it may be moved to and fromi Set screws 6 are threaded" 4 closed position. into the guides 3 and engage the gate 4 to hold it in any position to which it mayhave been adjusted. A pipe 7' leads from the sewage disposal plan 1 to a filter 8. There is a valve 9 or other suitable means by which the "5515 flow through the pipe 7 may be controlled. A.

supplemental tank 10, forming part of the by-pass system, is located at oneend of the sewage disposal plant 1. A pipe llleads from r the tank 10 to a cess pool 12, and there is a valve 14. in the pipe 11. A pipe connects Figure 1 shows in plan, the devices formthe sewagejdisposal plant 1 with the cess pool 12, and in the pipe 15, there is a valve 16, the valves 16, 14, and'9 being under the control of an operator. 7

The outfall line of the system is marked by .'.the numeral 17, and leads to a river 18 or other body of water which takes care of the sewage ultimately. The outfall pipe 17 has a branch 19 communicating with the cesspool 12, and

I branch 20 1com1nunicatingwith the fil- In the inlet pipe 2 is an opening 21' which communicates with the supplemental tank 10. An anchor 22,.s'uch as an angle member, is secured to'the pipe 2Iwithin the tank 10. A foot-piece 23, intheform of an angle member, is mountedonthe pipe 2 and extends lengthing 21 inlthe pipe 2. Grate bars 24 connect thefocit-piece 23 and the anchor 22. Tie rods 25extend circ'umferentially of the inlet pipe 2. their outer'en'ds, the tie rods 25 are connected at 26to the pipe 2. The inner ends ofthe tie rods 25 pass through the foot-piece 23. Nuts27 arejthreaded on the tie rods 25 f and bear againstthe foot-piece 23. Owing to the adjustmentthus'provided, the grate bars finay bespaced affproper distance from the pipe 2, so as to retain a curved gate 28, inthe The gate 28-has outstanding handles 29 which cxtend betwecn the gratebars 24 and hold the gate 28 in place. I The grate bars 2 1 bind the gate 28 frictionally against thcpipo '2, undeifthe action of the nuts 27, but-it is possible to shift the gate28 by means of the l1andles29, so that the gate covers 10017911- ing 21 more or less.

A tubular metal base -30 is'provided and is connected to a hopper 31 which may support a manhole 32, indicatedinFigure 1.

The numeral 33 designatesan annular supporting frame madefup of abottom member 34 which is approximately semi-circular in forn'nas Figure -3'will showr The supporting 'e-a'm sza in'cludes'atopj member 35 which, also, is approximately semi-circular-in form. The members 34. and 35'have cars 36 that extend outwardly through openings in the tubular base 30. The cars 36 are joined by tightening devices, such as bolts 44, and through the instrumentality of the bolts 44, the frame 33 may be clamped on one end of the pipe 17, the said end of the pipe 17 entering the trough-shaped base 30. The opposite portion of the pipe 17 is extended into the end of the arm 40 there is a weight 42 which may be adjusted lengthwise of the arm, the weight being held in adjusted positions by a set screw 43 which is threaded into theweight 42 and engages the arm 40. On the lower end of the arm 40 there is secured a valve plate 41 which bears against one end of the pipe 17 and closes toward the filter 8, that is, away from the river 18. The weight 42 may be so adjusted on the arm 40 that the plate 41 will not bear with much pressure against the. end of the pipe 17.

In the ordinary operation of the device, the sewage can push the valve 41 open and escape through the pipe 17 into the river 18. 1

If, however, the water in the river rises unduly, the valve 41 will be held closed, and the water will be prevented from backing up intothe sewer system. a

The gate 4 is set to regulate the amount of sewage that goes into the disposal plant 1, and the pipe EZjmay be closed entirely by the gate 4, if desired. The sewage then travels ing the frame on the pipe, an arm pivotally mounted intermediate its ends on the frame, a valve carried by one end of the arm and cooperating with the pipe, and a counterpoiseweight on the opposite end of the arm.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

through the by-pass represented by the sup plemental tank 10, the pipe 11, and the pipe 19, into the pipe 17, and from thence lnto the river 18'.

The amount of liduidithat flows through the opening 21 in the pipe 2 into the tank 10 may be regulated by shifting thefgate 28.

The solid matter is held'back by the grate bars 24 and passes on into the disposal plant 1, to be handled in the usual way.

h at is claimed is: v

1. In a device of the class described, a base having openings, a pipe extended into the base, a frame comprising cooperating members having ears extended outwardly through the openings, connecting devices joining the ears and located externally of the base, the connecting devices holding the frame on the pipe, an arm pivoted to the frame, and a valve carried by the arm and cooperating with the end of the pipe.

2. In a device of the class described, a base havingopenings, a pipe extended into the base, a frame arranged about the pipe and comprisingcooperating members having ears extended outwardly through the openings,
